B
Vertex angle for regular hexagon = 180∘(6−2)6=30∘×4=120∘
In the ΔABC, ∠ACB = ∠CAB = 30∘
We know 30∘ - 60∘ - 90∘ = 1 : √3 : 2 ; AC = 2√3
Now, from ΔACD:-
12 + (2√3)2 = AD2;AD = √13.Option (b)
The starting point of Ram is A and end point is D.
Alternate Solution:
The answer option will have to be between 2√3 and 4 i.e. between √12 and √16.
Only option (b) fulfils the given condition and hence option (b) is the correct answer choice.
